Serial Interface Mode
In the Serial I/F Mode, the ML9044A interfaces with the CPU via the
CS, SHT, SI and SO pins.
Writing and reading operations are executed in units of 16 bits after the
CS signal falls down. If the CS signal rises
up before the completion of 16-bit unit access, this access is ignored.
When the BF bit is “1”, the ML9044A cannot accept any other instructions. Before inputting a new instruction,
check that the BF bit is “0”. Any access when the BF bit is “1” is ignored.
Data format is LSB-first.
Examples of Access in the Serial I/F Mode
Note 1: Higher 5 bits of each instruction must be input at a “H” level.
Note 2: Lower 8 bits are “don’t care” when the instructions in the READ MODE are set.
Note 3: After one instruction is input, the next instruction must be input after the
CS pin is pulled at a “H” level.
